Abstract:Not Available We propose to develop an optical profilometer that can quantitatively measure the shape of compressor blades in an operating turbine engine. The instrument performs the measurement using a single pulse of light and can therefore, freeze the motion of the blade. This instrument can be… more

Abstract:Volatile organic carbon (VOC) and sulfur-containing compounds are quite prevalent in many shipboard and base operations, and create noxious odors and health hazards upon release to the environment. it is proposed to utilize the ability of microorganisms to completely mineralize these compounds using… more
Abstract:ADJUSTABLE SPEED THREE-PHASE AC MOTOR DRIVES ARE NOW PREFERRED OVER DC MOTOR SYSTEMS, FOR MANY INDUSTRIAL DRIVES, AND BATTERY-POWERED CARS. THIS IS BECAUSE STATIC INVERTERS, WITH ADJUSTABLE FREQUENCY AND VOLTAGE, ARE RELIABLE AND ECONOMICAL. INDUCTION MOTORS PROVIDE BRUSHLESS OPERATION, BUT THEY… more
Abstract:INVOTEK WILL DEVELOP A LIGHT SENSITIVE KEYBOARD AND A LASER LIGHT SOURCE FOR ACCESSING APPLE 2GS AND MACINTOSH COMPUTERS. THIS KEYBOARD SYSTEM WILL INCORPORATE A LIGHT DETECTION SCHEME WHICH WILL INSURE USER EYE SAFETY. THE SYSTEM WILL ALLOW PEOPLE WITH SEVERE PHYSICAL DISABILITIES TO ACCESS AN… more
Abstract:Current highway and runway deicers include rock salt, urea and glycols, all of which are toxic to vegetation or aquatic life or are corrosive to bridges and vehicles. In some areas, deicing runoff must be confined for subsequent treatment. Calcium magnesium acetate (CMA) is very expensive ($650) per… more
Abstract:ABOUT 100 TRILLION CUBIC FEET OF PROVEN AND FUTURE NATURAL GAS RESERVES ARE EXPECTED TO HAVE HIGH HYDROGEN SULFIDE (H2S) CONCENTRATIONS, REQUIRING TREATMENT AND REMOVAL. CURRENT TREATMENTPROCESSES ARE EXPENSIVE, EMIT LARGE QUANTITIES OF SULFUR GASES TO THE ENVIRONMENT, AND CAN BE APPLIED ONLY TO… more
Abstract:ATMOSPHERIC CONCENTRATIONS OF METHANE ARE CURRENTLY INCREASING AT A RATE OF ONE PERCENT ANNUALLY. EMISSIONS OF THIS GREENHOUSE GAS FROM COAL MINES NOW AMOUNT TO ABOUT 65 MILLION TONSANNUALLY, AND ARE INCREASING STEADILY. METHANE ADSORBED ONTO INTERNAL COAL SURFACES IS RELEASED AS THE COAL IS MINED.… more
Abstract:GASOLINE BLENDED WITH FUEL OXYGENATES PRODUCED FROM COAL HASSEVERAL SIGNIFICANT ADVANTAGES OVER CONVENTIONAL GASOLINE, INCLUDING REDUCED POLLUTANT EMISSIONS, LESS DEPENDENCE ON IMPORTED OIL, AND INCREASED OCTANE QUALITY. ALCOHOLS AND ETHERS HAVE RECEIVED PRIMARY INTEREST AS FUEL OXYGENATES BECAUSE… more
Abstract:INVOTEK WILL BUILD AND EVALUATE A SECOND GENERATION PROTOTYPE WHICH PROVIDES CONSTANT FEEDBACK TO STUDENTS WITH ATTENTION PROBLEMS. THE SYSTEM OPERATES ON THE PREMISE THAT GIVING A STUDENT POINTS TOWARDS PREDEFINED ON-TASK GOALS WILL MODIFY HIS/HER BEHAVIOR. THESE POINTS ARE ACCUMULATED ON THE… more
Abstract:INVOTEK WILL DEVELOP A ROBOTIC ARM FOR TRANSFERRING HOSPITAL AND NURSING HOME PATIENTS. THIS DEVICE WILL NOT ATTEMPT TO ADDRESS EVERY LIFTING SITUATION. INSTEAD, INVOTEK WILL CONCENTRATE ON THE MOST COMMON LIFTING SITUATIONS FOR THE MAJORITY OF PATIENTS. THIS FOCUS WILL ALLOW INVOTEK TO DESIGN A… more
Abstract:FOR THE MAJORITY OF NON- VOCAL STUDENTS WITH COGNITIVE IMPAIRMENTS, THE MOST APPROPRIATE COMMUNICATION SYSTEM INVOLVES GRAPHICS (SIMPLE SYMBOLS OR PICTURE).

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
